Efficient Battery Usage in Wireless-Powered Cell-Free Systems with Self-Energy Recycling

no code implementations28 Dec 2022 Iran M. Braga Jr., Roberto P. Antonioli, Gabor Fodor, Yuri C. B. Silva, Walter C. Freitas Jr

This paper investigates wireless-powered cell-free systems, in which the users send their uplink data signal while simultaneously harvesting energy from network nodes and user terminals - including the transmitting user terminal itself - by performing self-energy recycling.

Joint Resource Allocation and Transceiver Design for Sum-Rate Maximization under Latency Constraints in Multicell MU-MIMO Systems

no code implementations29 Mar 2021 Iran M. Braga Jr., Roberto P. Antonioli, Gabor Fodor, Yuri C. B. Silva, Carlos F. M. e Silva, Walter C. Freitas Jr

This problem is motivated by the observation that multicell MU-MIMO OFDM systems serve multiple quality of service classes and the system performance depends critically on both the transceiver design and the scheduling algorithm.

Deep Reinforcement Learning for QoS-Constrained Resource Allocation in Multiservice Networks

no code implementations3 Mar 2020 Juno V. Saraiva, Iran M. Braga Jr., Victor F. Monteiro, F. Rafael M. Lima, Tarcisio F. Maciel, Walter C. Freitas Jr., F. Rodrigo P. Cavalcanti

In this article, we study a Radio Resource Allocation (RRA) that was formulated as a non-convex optimization problem whose main aim is to maximize the spectral efficiency subject to satisfaction guarantees in multiservice wireless systems.
